Dark blue (#111184) embodies the profound depths of the night sky, combining sophistication with unwavering stability. This rich, deep hue sits between the authoritative presence of navy blue and the mysterious allure of midnight blue, making it perfect for creating trustworthy, professional interfaces.

In design psychology, dark blue promotes mental clarity and focus while conveying reliability and wisdom. It's an excellent choice for corporate branding, financial applications, and healthcare platforms where trust is paramount. The color works beautifully as a background in dark mode interfaces, reducing eye strain during extended use.

For striking combinations, pair dark blue with cream or silver for elegant contrast, or emerald green for a luxurious, regal palette. Avoid pairing with harsh neons like neon orange, which create overwhelming visual conflict.

Whether used as a primary brand color or accent shade, dark blue's timeless appeal bridges traditional authority with contemporary sophistication, making it ideal for designs that need to project both innovation and dependability.
